Closed Looped Systems
Reclaimable media is used exclusively in closed-loop blasting facilities, these include cabinets, blast booths, and centrifugal wheel systems.
Blast cabinets are a small closed-loop system, where the operator processes small components by manipulating an internal blast nozzle using integrated rubber gloves. The cabinet itself has four modules that make up the system, these being the containment, blast media, a set of media resistant gloves, and the recycling unit. The cabinet also comes with a window where the operator views the component they are processing, and a foot pedal to mediate the flow of the blast nozzle. There are two variants of blast cabinets: suction and direct pressure systems. Direct pressure cabinets operate at higher pressures, while suction systems draw the media into an airstream and blasts at lower pressures.
Blast booths are an upscaled version of a blast cabinet. Within these rooms, operators manipulate a blast hose and nozzle to abrade heavy industrial components. To operate in these rooms staff must be trained in blasting technique and safety. Blast rooms can come in a range sizes and can accommodate very large or uniquely shaped objects, such as rail cars, commercial or military vehicles, construction equipment, ship sections, and aircraft. Like cabinets, blast rooms function on the same premise of the four-module system with some additional features and can be designed to fit bespoke needs.
Also known as an “Airless blasting”, wheel blasting machines are self-contained units that use reclaimable abrasive. Wheel blasting machines utilise a rotating centrifugal wheel to propel abrasive at exceptional speeds. These machines come in a range of sizes and are fitted with conveyors and generally automated.
